"The Great Pig War (aka the San Juan Boundary Dispute) between the US and UK/Canada lasted seven whole years. At maximum belligerence, the order of battle included 2,600 ground troops, five powerful ships of the line, and nearly a hundred cannon.

But fortunately, the combatants never actually got around to doing much combatting. In fact, the only recorded injury was a Royal Marine who got hit in the eye by a rock thrown from the American trenches. He was shipped to a nearby militry hospital, recuperated, and eventually rejoined his unit.

Most of the opposing troops' energies were spent sneaking across the lines to each other's outposts - to play cards, swap stories, and to trade American tobacco and fresh food for navy rum swiped from the British quartermaster's stores.

Generally acknowledged as The Best War Ever."
